To attempt to answer this question myself, I pulled up official sales figures from the IRS:
https://www.irs.gov/businesses/irc-30d-plug-in-electric-drive-motor-vehicle-credit-quarterly-sales
The cumulative sales plot is essentially linear, but if you plot the yearly sales it appears to be closer to exponential, as you might expect, but in two waves/phases:

The question is, why the big drop between 2018 and 2019? That's pre-pandemic, so the accompanying societal disruptions can't explain it. The i3 came on the market in 2017 and while it is on its way out, is still being sold. Is there some other popular BMW PHEV the production of which was stopped in 2018? Or did EV/PHEV sales in general just take a dip that year?
Anyway, skating out onto thin ice and fitting an exponential function to yearly sales in 2019, 2020, and 2021 (not quite complete), I estimate that the 200,000 threshold will be reached during the 3rd or 4th quarter of 2023 - IOW, about the time the new SE is supposed to make it to market!
(And yes, I realize that changes in the tax law have been proposed - including excluding vehicles built in China - that could impact all of this.)
